Frustrated with caloric burn calculations.

I did 3 sets of tabata (10 repetitions, 25 sec work, 10sec rest) fast skipping. how do you calculate that? MFP gave me like 100 calories and I KNOW it was way more than that!
Also, I tied my backpack to a sled and took my son (40lbs) for a run around the school soccer field, 3 laps (tabata style) plus walking to and from field, 14 mins work. How do I calculate that?

    Use an online calculator and as for the 40 lbs you would have to add that to whatever weight you currently are to get an estimate. It won't be accurate since that weight isn't a tissue or cell that uses energy but it will induce stress on other cells of your body to work harder

    If you're trying to lose weight, I wouldn't log into mfp the amount of calories burned. It'll re-adjust your calories for the day, and you may fall into the trap of eating back those burned calories.

    If you'd like to log your activity strictly for the sake of keeping track, then just log it as an activity without the calorie factor.

    OOPs correction the running would be more like HIIT.

    Yeah, I did eat them all back at first but now I heard to only eat 25-50% back. If I dont eat some back I get super hungry and have trouble sleeping.

    Why would you not eat the calories back? This is math, plain and simple. If you're trying to lose weight, MFP sets a low calorie goal for you which will allow you to lose weight. It then adds any exercise calories to the already-low daily calorie goal. So if you eat those calories, you are still low enough to lose weight.

    That said, I'll buy into the theory that MFP overestimates calories burned and I do not eat them ALL back, just in case that's true. But honestly, I don't think MFP overestimates calories that much.

    I've lost 25 pounds (which is all I needed to lose) and am in pretty good shape, so this seems to be working for me. I love eating. Sue me. I exercise so I can eat, and it works.

    Why don't you want to use a heart rate monitor?

    agree w. @CindyFooWho. MFP already calculates your defecit assuming you will eat back all the calories from exercise. if you eat back less than that you will be at a greater defecit than your stated goal. only reason not to eat back is if you think MFP is overestimating, which could be true.

    all that aside, if the scale is moving down then you are doing it right.

    i have gone and back-calculated my true TDEE based on calorie intake and average weight trends, and MFP's target was way off. i just use their calorie logging and weight logging, and more or less ignore the targets. just weigh yourself and re-adjust your calorie target based on trends.

    Heart rate monitors are designed for steady state cardio. No hiit, not strength training, not circuit training....those are still a guess.

    Ok good to know. Also, HIIT and tabata stimulate fast twitch muscle fibres. I think that makes a difference in calories burned.

    Wouldn't bother wasting the money, they're not designed for what you're describing.

    fwiw even 100 cals seems a bit optimistic.

    Doubt it was 100 calories for that short a duration.
    Don't confuse high effort / feeling hard with high calorie burns.

    Agree, what you described is 12.5 minutes of exercise with rest breaks mixed in. 100 doesn't sound like a bad estimate.

    Agreed, a HRM is good for steady state cardio, not tabata, weight training, etc. Also, an online article I read said tabata burns maybe 15 cals/minute (which is awesome) but even 100 would be a little high, actually.

    100 calories is probably exaggerated but close.

    and echoing the HRM thoughts. Not really good for this type of stuff.

    I did 15 minutes of tabata, thats 225 calories at 15 cals per min. 100 is not that close to 225 when it comes to cals. I read somewhere that you count the rest because your hr is still up at rest.

    No one is burning 225 cals in 15 minutes. Where are you getting that number? From the database?

    15 cals a minute? Not likely.

    And HR does not directly correlate to calorie burns so no, you shouldn't be counting rests.

    Here is one resource, im too tired to go through them all and post them but if you really want to know you can google it.

    "Researchers found that during the workout subjects averaged 86 percent of their maximum heart rates and 74 percent of their VO2maxes, measures that meet or exceed industry guidelines for improving cardio fitness and body composition. On the Borg Scale of 6 to 20, the participants gave the sweat sesh a 15.4 rating of perceived exertion (RPE)—i.e. “hard”—and burned 240 to 360 calories. With an average of 15 calories torched a minute, the findings of this study support that total-body Tabata-style workouts can prove powerful in terms of enhancing health and facilitating weight loss.:

    What the heck, one more...

    1/ Tabata Time
    The Tabata protocol is an extremely high-intensity training method that produces results very quickly. A Tabata workout or sequence is an interval training cycle of 20 seconds of exercise performed at maximum intensity followed by 10 seconds of rest, repeated eight times for a total of four minutes.
    The Burning Edge: A study conducted at the National Institute of Fitness and Sports (Japan) found that subjects who performed Tabata five days a week for six weeks improved their maximum aerobic capacities (a measure of the highest amount of oxygen consumed during maximal exercise) by 14% and anaerobic capacities (a measure of maximum output over a short period) by 28%. In a nutshell, the extremely short rest periods of Tabata force your body to move between energy systems, producing vast amounts of lactic acid and growth hormone that push your body into accelerated fat-burning mode for hours postworkout.
    Burn 500 in: 26 minutes
    TIP: To reach your goal of burning 500 calories, perform four separate Tabata intervals, each four minutes in length. Include a five-minute warm-up and cool-down.

    Neither of which are sources I'd give any credence to.

    There is much nonsense written about HIIT.

    I knew someone was going to say that.

    In the past, I lost 30lbs in 3 months without changing my diet, doing only HIIT. And I kept the weight off until this past surgery.

    If you are able to burn 15 a minute without him attached then you are obviously extremely, extremely fit. Just guess like you've been doing if it's working.

    Oh no no no, I'm not extremely fit, I was a couple years ago, but then I put on 30lbs of fat after a surgery and bedrest. Trying to lose 10lbs of fat and add 10lbs of muscle and then ill decide what to do about the rest of the fat, because being at 19% bodyfat made me look too skinny and old. That being said, I am not extremely fit but I work hard when I work out, to the point of feeling like im going to throw up. Ever feel that way?

    Burning 15 a minute is going at max intensity, HR up and sweat pouring ect... That is if it is true, now you got me doubting what I learned in personal trainers courses, so Ill have to do more research, but then, how do I know whats legit information and what isnt? By the looks of your profile picture, you must know what your doing so Im not discounting what you say..
    Its like the vaccine wars, some resources prove they are harmful, don't work as well as they claim, and then some resources say they are good and helpful.. Each side will say that the others resources are not credible.
